General description

Palladium(II) acetate is a homogenous oxidation catalyst. It participates in the activation of alkenic and aromatic compounds towards oxidative inter- and intramolecular nucleophilic reactions. Crystals of palladium(II) acetate have a trimeric structure, having symmetry D3h. Each of the palladium atoms in the crystals are joined to the other two by double acetate bridges. Microencapsulation of palladium(II) acetate in polyurea affords polyurea-encapsulated palladium(II) acetate. It is a versatile heterogeneous catalyst for various phosphine-free cross-coupling reactions. It participates as catalyst in the Heck coupling reaction of pthalides with different alkenes.

Application

Palladium(II) acetate was employed as a catalyst for the following reactions:
  • Formation of allylic acetates. (eq. 1)
  • Hydroselenation of triple bonds. (eq. 2)
  • Heck arylation of alkenes. (eq. 3)
  • Cyclocarbonylation. (eq. 4)
  • Buchwald-Hartwig amination reaction. (eq. 5)

  4. What is Product 520764, Palladium (II) acetate, soluble in?

    Palladium acetate is not water-soluble; it is organic soluble. Although Sigma-Aldrich does not test solubility of 520764 directly, it is expected to be soluble in most common organic solvents, like chloroform, methylene chloride and acetone, according to the manufacturer.

  5. When using are Product 520764, Palladium (II) acetate, what can I use to remove traces of palladium that this catalyst may leave behind?

    We would recommend using a metallic scavenger like the QuadraPureTM products. Product numbers 655422 and 657662 are designed to scavenge palladium ions and are effective in both acidic and basic conditions. The resins are capable of removing metallic contamination to very low levels and are ideal for pharmaceutical or fine chemical processing.

  6. What is the difference between Product 520764, Palladium (II) acetate, and the palladium acetate in the form of a ChemDose® tablet?

    The ChemDose® products offer a streamlined way to catalyze reactions. The catalyst is dispersed in an inert tablet matrix in specific millimolar and micromolar quantities. The tablets can decrease time spent on weighing/adding the catalyst to the reaction mixture. The tablets effectively give the same reaction yields with a controlled release of the catalyst. They are also extremely easy to remove after the reaction is complete. The inert tablet usually stays intact throughout the reaction. Product 684929 is the ChemDose® tablet that contains 2.0 μmol of palladium (II) acetate, while product#: 685593 is the 10μmol version. More information on these products can be found at the link below. 

  7. What atmosphere is Product 520764, Palladium (II) acetate, packaged under?

    This material is packaged under a layer of nitrogen to reduce the chance of moisture contamination.
